Hi, so I just upgraded my main monitor from an ancient LG to a new Dell 27" (U2713H), it is connected via minidisplayport (to a gt120) and it all seems to work fine, however when playing back quicktimes in qt player, avid or even watching online I get a colour shift flicking from correct colour to a cooler version mid playback. It is almost everytime usually around four seconds in. When I stop playback the colour goes back to normal. Nothing else on the screen changes and there is no change to playback on my external broadcast (via BM card) or on my old Lacie palette monitor. I doubt whether this is a dell issue as it is only on the QT not the whole screen. I am stumped.

osx 10.7.5, MacPro 3,1. 12 gig ram. GT120 + GTX285, 12 TB raid, BM Card...

I've exactly the same problem with my GT120 & GTX285, with displayport or D-DVI. Any solution?
I found other persons with the same problem in the web but any solution yet...
